Docker
I use
-u "$(id -u):$(id -g)"
-e "DOCKER_USER=$USER"
and when I stop it, docker start it
is exit by usermod: user 'coder' does not exist

[roroyu]

maybe I use this before restart

sudo groupadd docker -g 999
sudo usermod -aG docker roro

[roroyu]

I try it again
Maybe just use -e "DOCKER_USER=$USER"
And cannot restart docker
